The South African shelduck or Cape shelduck (Tadorna cana) is a species of shelduck, a group of large goose-like birds in the bird family Anatidae, which includes the swans, geese and ducks. This is a common species native to southern Africa.
This is a 64 cm (25 in) long bird which breeds mainly in Namibia and South Africa. In the austral winter, many birds move north-east from the breeding range to favoured moulting grounds, where sizable concentrations occur.
This species is mainly associated with lakes and rivers in fairly open country, breeding in disused mammal holes, usually those of the aardvark. Pairs tend to be very nomadic when not in breeding season. The South African shelduck was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other geese, ducks and swans in the genus Anas and coined the binomial name Anas cana. Gmelin based his description on the "Grey-headed goose" from the Cape of Good Hope that the English ornithologist John Latham had described in 1785 in his A General Synopsis of Birds.

Rare
Under 5% of wildlife watchers report a South African Shelduck sighting in Cape Town on a given day, based on 48 verified sightings from GBIF citizen-science data. It is the 134th most-seen of the 196 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report a South African Shelduck in Cape Town on a given day, against under 5% in March to January, the lowest months. That is one of Cape Town's driest months, with about 15 mm of rain against 140 mm in June.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most South African Shelduck sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 4 cities where we can rate South African Shelduck sightings, Cape Town has the highest daily chance: under 5%. Next come Pretoria (South Africa, under 5%) and London (United Kingdom, under 5%).
Same family: Anatidae
The closest relatives of the South African Shelduck that you can see in Cape Town (family Anatidae, Ducks, Geese, and Swans) are Egyptian Goose (about 60%), Yellow-billed Duck (about 40%) and Cape Shoveler (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the South African Shelduck is recorded against all the birds logged in Cape Town (48 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
